  • An issue may be that the network may, for the purpose of managing de-configuration of component carriers, configure more than one measurement object (one per frequency), each including one reporting configuration and one measurement identity.
  • the concerned carrier may have a special role with respect to the connection to the network, for example, if it corresponds to a special cell or a primary serving cell in an existing method, loss of connectivity to the network may occur.
  • the network may reconfigure the WTRU so that the primary serving cell corresponds to a carrier from which the signal quality may be acceptable. Such a reconfiguration may require that the network have information on the quality of the other carriers early enough after either the WTRU may measure the loss of quality of the carrier and/or the WTRU may be notified of the loss of quality of the carrier corresponding to the primary serving cell.
  • the WTRU may report measurement results pertaining to cells on the same frequency as this cell.
  • the network may not obtain information about other cells immediately on the other frequencies, unless perhaps another event would independently have been triggered at the same time, or a periodic report would have been transmitted at about the same time for one of the other frequencies.
  • the delay may result in the WTRU losing the connection to the network, even though this may have been avoided with a reconfiguration.
  • Similar issues may occur due to a configuration of cells on multiple component carriers (CCs) that may be included in a handover command.
  • the network may not have the most recent measurement results on the other carriers on the target base station, except perhaps the one that may have triggered the measurement event reporting.
  • the network may determine, perhaps based on a requirement, when to add or remove serving cells from the configuration of a WTRU that may be capable of operating with multiple carriers. At least one factor in such a determination, especially perhaps in a scenario where the coverage area may be different between the different available carrier frequencies, may be the measurements taken from these carriers. In such scenarios, where feasible, the measurement results may be available at the right time.
  • a measurement event may not exist to report deterioration in the quality of one of the configured carriers if at least one of the configured carriers drops below one or more thresholds.
  • FIG. 2 At least one view of this problem may be seen in FIG. 2 .
  • the WTRU may not require high data rates and therefore may continue to operate with a single carrier when the signal quality of a neighboring component carrier (CC) may become higher than (or rise above) a threshold.
  • the network may not know whether the signal quality of the neighbor component carrier (CC) may be still good enough to be reconfigured, at least because no measurement event may exist to report that the neighboring component carrier (CC) may become lower than (or fall below) a threshold.
  • Typical procedures for the handling of measurement identities at an inter-frequency handover or re-establishment may not be directly applied to scenarios where the WTRU operates with multiple carriers in either the source or target configuration.
  • an issue may be that the swapping of measurement objects (MeasObjects) for each measurement identity (Measld) corresponding to one or more events may result in meaningless configurations on some carriers. This may occur, for example, when the frequency corresponding to the primary component carrier (PCC) in the source configuration may not be a configured CC in the target configuration, while the frequency corresponding to the PCC in the target configuration may be a configured CC (i.e. a secondary component carrier (SCC)) in the source configuration.
  • the swapping of measurement objects may result in meaningless events, such as "serving cell becoming higher than a threshold" on a frequency where there may be no serving cell. Meaningless events such as these, for example, may result in unnecessary measurements on certain frequencies.
  • a similar issue may arise in a reconfiguration where a frequency may be part of the source configuration as SCC, but not part of the target configuration.
  • a frequency may be part of the source configuration as SCC, but not part of the target configuration.
  • the concerned measObject may not be involved in any swapping, meaningless events may end up in the target configuration.
  • the WTRU may be configured with an "S-Measure” parameter.
  • the "s-Measure” parameter may, for example, be a quality threshold for the serving cell that may control whether or not the WTRU may, or perhaps be required, to perform measurements of intra-frequency, inter-frequency, and inter-RAT neighboring cells.
  • a multi-carrier capable WRTU may refrain from measuring on non-configured frequencies as long as the signal strength on the primary serving cell may be above a certain configured s-Measure. This may hinder the network for the eventual configuration of additional CCs for this WTRU.
  • a measurement configuration may include multiple measurement objects, such as for more than one component carrier or frequency.
  • One or more methods may be used to minimize the possibility that a WTRU generates and transmits multiple measurement reports within a short period of time. This may be achieved, by way of example and not limitation, by grouping measurements, based on measurement identities. This may be achieved by applying logic governing a trigger condition for initiating the transmission of a measurement report.
  • minimizing the possibility that a WTRU generates and transmits multiple measurement reports within a short period of time may also be achieved by initiating transmission of one or more various types of reports.
  • at least one of these types may be a report of only the measurement or measurements for which an event was triggered.
  • Another type may be a report for all measurements of the measurement group.
  • Another type may be multiple reports, perhaps at the same time, each containing measurement results pertaining to a single measurement object.
  • This latter type may be distinct from, and may have advantages in some scenarios over, the near-simultaneous transmission of multiple reports, since it may result in the transmission of reports in one transmission time interval (TTI). This may generally result in less overhead than if they are transmitted in different TTIs.
  • TTI transmission time interval
  • a measurement identity may be defined that associates one or more measurement objects (measObject), for example, a frequency, with one reporting configuration.
  • a reporting configuration may include a list of criteria and reporting formats.
  • Embodiments contemplate a realization for multicarrier operation may be as follows: the measurement identity may be additionally configured with one new parameter representing the group of measurements (measGroupID), which may itself be associated with a type (measGroupType) indicating the triggering function to apply to the group of measurements.
  • measGroupID the group of measurements
  • measGroupType the type of measurements
  • the associated triggering function may be one of several types. At least one type of triggering function may be referred to as a default triggering function.
  • the WTRU may, perhaps immediately or with a predetermined delay, initiate one or more procedures to transmit a measurement report for the measurement group.
  • At least one type of triggering function may be referred to as a window-based triggering function.
  • the WTRU may consider that this measurement report is pending and may wait for a certain period of time, (i.e. a window of time). Once the period ends and there is at least one pending measurement report, the WTRU may initiate a procedure to transmit a measurement report for the measurement group.
  • the size of the window may be either a fixed value or may be configured by the network.

  • the configuring may be performed using L3 signaling, such as RRC.
  • Embodiments contemplate that at least one type of triggering function may be referred to as a cascaded time-to-trigger triggering function.
  • a time Tx may be defined as a delay before the WTRU may initiate transmission of a measurement report, that is, a time-to-trigger, for example.
  • the WTRU may, for example, start a first timer corresponding to a value T1.
  • the WTRU may complete an evaluation of other measurement objects in the measurement group that may be configured with a second timer, T2, where, for example, T2 may be smaller than T1.
  • the WTRU may report quantities for measurements that satisfy the event criteria in the same measurement report transmission.
  • the respective values of Tx may each be either a fixed value or may be configured by the network using, for example, L3 signaling such as RRC, for example, such that TI and T2 may be multiples of the measurement occasion. This may reduce the fluctuation of different measurements for entering the time-to-trigger timers.
  • a parameter may be included to indicate whether or not only the measurement or measurements for which an event was triggered may be reported.
  • the WTRU may include in the transmission of the measurement report the quantities for some or all measurement objects of the measurement groups if the parameter may be true.

Alternatively, best cell may be used to refer to the measured cell that may not be part of the WTRU configuration that may have the highest metric on the given frequency.
